To allwhom tame concern: i 1

Be it known that I, THOMAS II. SEELY, a citizen of the United States,residing at Dorchester, Boston, in the county of Suffolk and State of.Massachusetts, have invented certain new and useful Improvements inInsole-Reinforcing Machines; and I do hereby declare the following'to bea full, clear, and exact description of the'inventio'n, such as willenable others skilled in the art to which itapp'ertains' to make and usethe same. I

This invention relates to machines for ap-j plying reinforcing materialto lnsoles WhlOll' are used in the manufacture of boots'and shoes, andmore particularly to mechanism for trimming thexcess reinforcingmaterial while it is beingapplied to the insole.

Heretofore, in using machines of the character referred to, thereinforcing material has been formedabout the lip and applied along themarginof the insole, step by step, and as the insole progresses throughthe machine cutters, guided by the contour of the insole, triin thereinforcing material along a line coinciding with its edge. One suchmachine is thatillustrated and described in the United States patent toJ .B. Hadaway No. engseo, dated November 29, 1898. After the insole isreinforced and the fabric is trimmed in the manner described in saidpatent the edge of the reinforcing material oftenbecoines loosened fromthe featherand its edge ravele'd out so that the threads of the fabricshow beyond the edge of the hi sole when viewed from its grain side."This condition is undesirable as it renderstheiii sole unsightly anddetracts from its selling qualities, "The object of the presentinvention is to improve the fabric trimming mechanism so as to overcomethe disadvantages heretofore experienced in trimming the fabric alongthe edge of the feather.

In accordance with this object, the inventioii contemplates theprovision, in a machine of the character deseribed in; said Hadawaypatent heieinb'efore referred to, of rotary eel-ramm ng knives! qonsaueeed anoint-ranged seas totsever the fabrie along a line within theedgelof the insole instead of coincident with said edge.

construction and arrangement of theiropei'rating mechanism so asftoeffect a severance of the fabric along line spaced from the edge of theinsole! I d The various features of the inventionwill be best understoodfrom an inspection bf the accompanying drawings illustrating thepreferred embodiment of the invention, in which s Figure 1, is a sideelevation of the machine" looking from the right and has parts about thetrimming knives removed in order to show the improved trimming knives;Fig. 2 is a detail view showing the relation of the trimming knivestothe insole during the trimming operation and Fig. 3 is a frontel'evation'of theparts shown in Fig. 2; I The preferredenibodiment ofthe invention is illustrated as applied to the insole r'e mforcingmachine shown in the patent to Hadaway Ne. 614,860 hereinbefore referredto, and reference maybe had to this patent fora detailed description ofthe machine and its mode of operation. As described in said patent, headframe A mounted on a base A carries the reinforcing tools and theiroperating mechanism; In this frame is also mounted a work support 0which is held vieldingl in workingposition. An inso'le having a piece ofreinforcing fabric reughlv applied to its lipped face is placed upon thesupport C, which may be lowered through-means of a treadle attached to bwith its lip againstthe beading finger e of the formerE. Theprojeetingmargin of the reinforeing material rests on the top of the beadingfinger. When in operating posit'ijen the insele is clamped between thesuppo'i't C and a bead forming tool which bears upon the ieinforcingmaterial on the feather of the insole. Rotation of the main cam shaft Bforces the presser tool D against the reinforcing material upon the faceof the in, sole mean of its connection With cam b? and; tacks thematerial against the inner fact of the lip. From this point a formingtee-1 F forced downwardly thtou'ghthe medium of cam 5 andby coeperationwith a finger pressesuie reinforcing'niaterial down along the outer sideofthe lip cont plet'ing' the formation of abead or crimp about thelip,while the stationary forming tool behind the forming tool F presses thefeinfo'rcin material down upon h the feather The rain h 'carrie's' a camwhich is connected with the lever 0 and this lever actuates a pawl forrotating the support G step by step so that after the material has beenpressed down upon the insole the presser tool D is raised releasing theinsole and a slide f moves the forming tool, F forward simultaneouslywhile the support 0 is rotated by the pawl 0 After the'tool F hasfinished its forward stroke it is raised and returned to its formerposition ready to repeat its operation on the insole preparatory tomaking another step.

i and preferably are,

All ,of the parts just described may be, substantially the same as thecorresponding parts in the Hadaway patent. I

The trimming mechanism to remove the excess reinforcing material fromthe edge of the insole, which forms the subject matter of thepresentinvention, comprising the rotary ,disk cutters m, m and theiroperating mechanism, is mounted in the rear of the support C and as theinsole with the reinforcing material attached thereto is fed forward theknives sever this excess mate-. rial. The cutter m is carried upon theforward end of; the shaft 2, andthecutter m" upon the forward, end ofashaft 3, these two shafts being mountedv in suitable bearings in acarriage 4. The carriage 4 is in the form of a yoke the twofarms ofwhich afford a double bearing for both of 'theshafts. yThe shafts 2 and3 'are rotated simultaneously in opposite-directions by means of a.pinion 13 mounted'upon the driving shaft 3 and meshing with. a

similar pinion on the'driven shaft 2. The shaft 3is extendedrearwardlybeyond the carriage4 and has a lateral lug 5 carried by itsouter end which isengaged by an actuating arm 6 attached'to the innerend of a stud shaft Smounted in abearing 9. The bearing 9 is carriedby'a standard 10 whichis attached to the head A. by means of a block 30and bolt 31. The shaft 8 is driven by a belt-pulley 11. Rotation of theshaft 8 will impart rotation vto the shaft 3 by means of the coupling 5-6 and the shaft will be rotated in the oppositedirection from 3 throughthe medium of the pinions 13 and12.

- .The irregular contour of an insolerequires that the trimmingmechanism shall be capable of a longitudinal movement so that itwillfollow the edge of the insole in trimmingoif the reinforcing material.The carriage 4. is mounted to move freely back and forth toward thesupport C upon a bar 17 which is pivotally connected at 18 to a pair 7of swinging levers 19 that. are fulcrumed at 20. to the head A. vTheinner end of the carriage 4 is adjustably connected to the bar 17 bymeans of a slotted sup.- porting arm 32 and set screw 33 which willallow for adjustment toward and away carriage is rigidly connected tothe bar 17 by means of the supporting arm 34. This mounting of thecarriage 4 upon the bar' 17 is such that the outer ends of the shafts 23arethrown' away from the head A and are raised above the plane of thesupport 0 so that the shafts are caused to extend'at an angle to thesupport C (see Fig. 1). This causes the knife m" to be located above thefeather and inside of the edgeofthe insole and the knife m to be locatedbelow it in a position to chamfer the edgeof the insole when. the knivesare operated. Consequently the reinforcing fabric is severed along alineinside of the edge of the insole.

One of'thelevers 19 has a projecting arm 21* which is arranged to have a:limited movement between the; adjustable stop screws 22threaded inbearings in the lugs 23 on the frameA, and said arm 21 is connected toone end ofa spring 24 the opposite end of whichis secured in one, of thelugs, 23. The forward bearing for the lever shaft 3 is squared-and hassecured thereto a guard frame 25 (Figs. 2 and 3) which is provided witha portion 26 extending over the shaft 3, forming atable over which'themarginal portion of the canvas travels as the insole is fed forward. Thefree end of this bearing has mounted thereon a sole gage '27. shown bestin Fig; 3,'just in advance of the cutters and opposite their bite. Thisgage, as is seen, is mounted for adjustment toward the cutters as theywear smaller. The gage 27 prevents the cutters from cutting" in toodeep, the size of the beveled string chamfered off being determined by alongitudinal adjustment of the guard 25 on the shaft journal. In orderto adapt the trimming mechanism for different thicknesses of insoles,the fulcrum -20 of the inner lever 19 is eccentrically mounted upon theframe A and when the adjust ment hasbeen made to determine the verti-.cal position of the knives m and m the positionof the eccentric fulcrum20 is secured by means of aset screw 35. I I That the cutting knives mand m/may be kept in proper adjustment and in close contact whiletraveling along the edge of the insole, the shaft 2 is arranged to havea longitudinal sliding movement in its-bearings in the carriage 4.;Surrounding. this shaft is a coiled spring; 14 which .bears against theinner end of the yokeof the carriage 4, and at its opposite end against,a collar 15 secured upon a shaft 2 so that from the head A, and theouter end of the nism, the gage 27 will be held against the upper edgeof the insole by the spring 24, while the knife we will be held by thespring 15 in close contact with the knife m. The spring 524 permits thegage 27 to move in and out in accordance with the width of the featherperforming the samefunction as the corresponding part on said Hadawaypatent. When the insole is started through the machine the knives aredug into the upper edge of the feather, as they project beyond the gagewhich bears on said edge, and consequently their cutting bite is withinthe edge of the insole. As a result the reinforcing material is trimmedat the inner edge of the bevel produced by the knives, that is along aline inside the edge of the insole. The adjustment of the carriage 4 bymeans of the slotted bar 32 and the secentric pin 20 will allow fordifferent thicknesses of feather so that the trimming mechanism issuitable for any size or style of insole.

Vhile the invention has been illustrated and described in connectionwith a machine for applying reinforcing fabric to insoles, it will beapparent to those skilled in the art that a rotary trimming mechanismmounted at an angle to the work support is equally well adapted to beused for retrimming the fabric after it has once been trimmed along aline coincident with the edge of the insole, and the invention is,therefore, not limited to use in a machine which initially applies theinsole reinforcing material.
